The Hobby Components micro charger is a tiny single cell (3.7V) lithium battery charger module which not only incorporates both battery charging protection and control, but also includes battery voltage & current over discharge protection and battery overload protection. Measuring only 27 x 14mm this tiny module can easily be incorporated into low power lithium battery applications.

The charger will accept power from either a 5V microUSB adapter or via a 4.5 to 6V power supply and will charge a connected single cell lithium battery at a rate of ~0.5A.

The battery can be connected via a JST XH-2.54 connector or by 2 large solder pads (BIN + & BIN -).

The module's output supplies the batteries nominal output of 3.7V (4.2V whilst charging) at a constant current of up to 2A (depending on battery and charger specification). An external device can be connected to this output via a 0.1” pitch pin header or via 2 large solder terminals (BOUT + & GND).

Victoria ★★★★★

The voltage display is a nice touch for a charger this small—it lets me see exactly where my battery is at. Charges my 3.7V cells reliably without fuss, and the protection circuit gives me peace of mind.

Hazel V. ★★★★★

I was pleasantly surprised at how simple this charger is to set up—just connect a power source and a 3.7V cell, and the protection circuit does the rest. The voltage cutoff works exactly as advertised, giving me peace of mind for my DIY battery packs.

Edward ★★★★★

Tiny board fits right into my charging setup, and the built-in protection means I don't have to babysit it. The voltage monitoring is a nice touch for a module this size.
